Exotic and Conventional Quarkonium Physics Prospects at Belle II: Search for a Partner State to the $X(3872)$ at the $D^{0}\bar{D}^{0}$ threshold
The Belle II experiment at the SuperKEKB asymmetric $e^+e^-$ collider at KEK, Tsukuba, Japan, is recording data since 2018.

Summary: | The Belle II experiment at the SuperKEKB asymmetric $e^+e^-$ collider at KEK,
Tsukuba, Japan, is recording data since 2018. The expected high luminosity of
$\mathcal{L}=8\cdot 10^{35}~$cm$^{-2}$s$^{-1}$ enables searches for yet
unobserved exotic hadronic states in B meson decays. We describe the search for
a partner state of the $X(3872)$ at the $D^{*}\bar{D}^{*0}$ threshold. The
reconstruction of charmed mesons is tested with experimental data corresponding
to an integrated luminosity of $504~$pb$^{-1}$ collected at the energy in the
center of mass of $\Upsilon(4S)$ in 2018, and $2.62~$fb$^{-1}$ in 2019. |
